Litigation from the 1993 World Trade Center bombing case has dragged on so long it’s a national embarrassment – and the Port Authority shouldn’t be allowed to delay it any longer, a victim’s lawyer told an appeals court yesterday.

Linda Nash suffered brain damage when a terror blast slammed a chunk of concrete into her head in a garage at the Twin Towers nine years ago.

Lawyers for the PA, the agency that owned the buildings, are appealing a lower-court decision denying them the opportunity to question Nash a second time – a move Nash’s lawyer called a delaying tactic.
